Find the length x in each triangle. Express your answer in simplified radical form.\r
\n" ); document.write( "\n" ); document.write( "long side is 12
\n" ); document.write( "x is the straight side
\n" ); document.write( "8 is the bottom of the triangle\r
\n" ); document.write( "\n" ); document.write( " \"x%5E2+=+12%5E2+%2B+8%5E2\"
\n" ); document.write( " = 144 + 64
\n" ); document.write( " = 208\r
\n" ); document.write( "\n" ); document.write( "Yip, but it's only wrong because the long side =shortest*middle. so \"12%5E2=x%5E2%2B8%5E2\"
\n" ); document.write( ".:\"144=x%5E2%2B64\" minus 64 on both sides
\n" ); document.write( "\"80=x%5E2\" now square root both sides
\n" ); document.write( "\"sqrt%2880%29=X\"
\n" ); document.write( "simplify the radical
\n" ); document.write( "80-->2*2*2*2*5, or 16(5); and 16 is a perfect square of 4. therefore,
\n" ); document.write( "\"sqrt%2880%29\"=\"sqrt%285%2A16%29\"=\"4sqrt%285%29\" Otherwise, you would have been completely right.
\n" ); document.write( "
\n" );
